a Schematic view of hydrogen bonds in l-Glu crystal cell as an example chiral biocrystals. Hydrogen bonds represented as springs in the model used for a description of chiral phonons. b, c Experimental and calculated THz CD and THz ORD spectra of Glu (b) and Gln (c). d Supercell of l-Glu used for the quantum mechanical (QM) computations of the THz spectra. e Normalized THz absorption (TA) spectra obtained from the calculations of the l-Glu supercell in d using the normal-mode analysis (vertical lines) and molecular dynamics (MD simulations at the QM level (solid surfaces). f Normalized TCD spectra from the same MD simulations at the QM level used for TA in e. g Superimposed structural variations of the l-Glu molecules at 1.31 THz.
